The invention discloses a high-brightness 90°C soft polyvinyl chloride sheathed cable material and a preparation method thereof. The high-brightness 90°C soft polyvinyl chloride sheathed cable material comprises the following raw material components in proportion by weight: polyvinyl chloride resin A 50 parts, polyvinyl chloride resin B 50 parts, plasticizer A 15-25 parts, plasticizer B 10-30 parts, plasticizer C 5-10 parts, plasticizer D 5-10 parts, nano mineral filler 40～70 parts, calcium zinc stabilizer 4～8 parts, molding agent 1～3 parts, lubricant A 0.2～0.8 parts, lubricant B 0.2～0.8 parts, antioxidant 1～2 parts and high pigment black paste 2～ 4 parts. The high-brightness 90°C soft PVC sheathed cable material of the present invention has good compatibility and thermal stability of each raw material component, obvious mutual promotion effect, good processing performance of the obtained cable material, obvious improvement of mechanical properties, and black brightness. And the fineness is significantly improved; the preparation method is simple and easy to control. |
